A quasi-ancient oriental apocalypse that has experienced the "Hundred Ghosts at Night" catastrophe. The traditional social structure has collapsed, and human beings are lingering in the remaining "cities" or "junctions" guarded by special forces. Outside the city is a dangerous area called the "Desolate Wilderness", filled with strange beings called "monsters and monsters".
After time traveling, he lost his memory, became extremely calm, and possessed a strong desire to survive and the ability to observe. Forced to deal with the strange world, he gradually shifted from passively saving his life to actively using the painting skin and system rules. He retains a trace of identification with "humanity" in his heart, but has to perform cruel performances and kill in order to survive.
